This dataset comprises multiannual ground temperature measurements with an hourly resolution from sixteen high elevation sites (3493-4377 m a.s.l.) in the Bale Mountains, Ethiopia. The repository consists of three compressed folders: "Ground_Temperature_Data", "GT_Logfiles", and "TM_Logfiles". The folder "Ground_Temperature_Data" contains the followings files in ods and csv formats (the date format is DD.MM.YYYY hh:mm East Africa Time): - "Hourly_Ground_Temperatures_Corrected": Compilation of corrected hourly ground temperature data from all GT and TM data loggers installed in the Bale Mountains. The time series of each logger begins with the start of measurement and ends with the last readout. Some time series contain data gaps. - "Information_Sheet_Data_Correction": Overview table regarding all modifications applied to any of the original ground temperature data. - "Hourly_Ground_Temperatures_Interpolated": Compilation of complete (i.e. interpolated) hourly ground temperature time series from all GT and TM data loggers (except TM08 and TM15 to TM17 for the period 1 February 2017 (first measurement) to 20 January 2020 (last read-out). - "Information_Sheet_Data_Interpolation": Overview table regarding the gap-filling method applied to interpolate any of the corrected ground temperature time series. The folder "GT_Logfiles" contains the original logfiles of all GT data loggers in text format (the date format is YYYY.MM.DD hh:mm:ss East Africa Time). The folder "TM_Logfiles" contains the original logfiles of all TM data loggers in text format (the date format is DD.MM.YYYY hh:mm:ss East Africa Time).

This research was funded by the Swiss National Science Foundation (SNSF, grant no. 200021E-165446/1) and the German Research Foundation (DFG) in the framework of the joint Ethio-European Research Unit 2358 "The Mountain Exile hypothesis". We thank the Ethiopian Wildlife Conservation Authority, the College of Natural and Computational Sciences (Addis Ababa University), the Department of Plant Biology and Biodiversity Management (Addis Ababa University), the Philipps University Marburg, the Frankfurt Zoological Society, the Ethiopian Wolf Project, and the Bale Mountains National Park for their cooperation and permission to conduct field work. We also very much appreciate the support of Beriso Kemal, Edris Abduku, Mohammed Kedir, Temame, Terefe Endale, Geremew Mebratu, Sabrina Erlwein, Lukas Munz, Julian Struck, Wege Abebe, Aschalew Gashaw, Katinka Thielsen, and Tiziana Koch, without whom it would not have been possible to install and maintain a comprehensive ground temperature monitoring network in the Ethiopian Highlands.
